A Giant Popliteal Artery Aneurysm with Leg Ischemia

Abstract

A 71-year-old woman presented with intermittent claudication of the right lower extremity, and cyanosis and coldness in the right toes. Enhanced CT showed two aneurysms above the right knee and in the popliteal fossa; the former extended close to the adductor hiatus, and the latter, a giant aneurysm, was thrombosed up to the trifurcation of the popliteal artery. She underwent surgery with a diagnosis of leg ischemia caused by thrombosed aneurysm of the right popliteal artery. First, the distal superficial femoral artery was exposed by incising the adductor magnus tendon via medial approach. Then, we performed aneurysmectomy, thrombectomy of the trifurcation vessels, and revascularization with saphenous vein graft in conjunction with posterior approach in a prone position. The postoperative course was uneventful and no complication was detected during the 8-month follow-up.
